KARACHI: Security agencies in Karachi on Wednesday arrested the key suspect behind the deadly June 2013 bombing which killed nine people and injured senior Sindh High Court (SHC) judge Justice Maqbool Baqar, DawnNews reported.

According to sources, the suspect – who is believed to have masterminded the attack on the senior judge – was taken to an undisclosed location for interrogation.
